Exposure Risks:
Workplace Safety

Because of the dangers associated with exposure to beryllium, various agencies restrict beryllium levels in the workplace. The National Institute for Occupational Safety and Health (NIOSH) originally recommended a standard of not more than 0.5 micrograms of beryllium per cubic meter of workroom air during an 8–hour shift. In a recent rule that recognizes the extreme hazards posed by beryllium, the Department of Energy (DOE) has set an even lower level of 0.2 micrograms per cubic meter during an 8–hour shift for DOE workers and federal contractors (Final rule, 10 CFR 850, Dec. 8, 1999). The Occupational Safety and Health Administrations beryllium limit for other workers is 2.0 micrograms per cubic meter during an 8-hour shift–an amount 10 times higher than the DOE level.

Despite these beryllium restrictions, there is no known safe level of exposure. Even minimal exposure to beryllium may cause chronic beryllium disease and other health problems in susceptible individuals (National Jewish Medical News).

Because small amounts of beryllium dust or fumes are so toxic, good safety practices require very strict controls regarding the use of beryllium. Adequate ventilation and exhaust systems, routine air monitoring, protective clothing, and approved respirators can minimize beryllium exposure. Change rooms, restricted areas, and decontamination areas can limit the spread of beryllium throughout the workplace or into the worker's home environment.
